Abstract: Le système décrit permet à l'utilisateur d'un téléphone mobile (11) d'utiliser les services d'un réseau intelligent (IN) spécifique de son réseau domestique, indépendamment du fait que le réseau (12, 13, 14) auquel il est connecté à ce moment peut assurer ou non le service en question. Quand l'utilisateur fait une tentative d'appel vers l'extérieur (étape 1), la signalisation associée est transmise par un canal de signalisation. Le centre mobile de commutation (MSC) (13) reconnaît l'identité du client (codée électriquement dans les signaux d'établissement d'appel) et il accède aux données concernant l'utilisateur, qui sont enregistrées dans un registre (14). Les données dans le registre (14) concernant l'utilisateur (11) comprennent un marquage l'identifiant comme un client du IN, ce qui provoque l'arrêt du processus d'appel par le MSC (13) et l'envoi d'un signal (2) ou protocole, au point de commande des services SCP (15) dans le réseau local de l'utilisateur. Le SCP (15) active à ce moment le profil des services de l'utilisateur et, décide sur la base de ce profil, de la nécessité de recevoir une information additionnelle de l'utilisateur (11), par exemple son numéro d'identification personnel (PIN) ou une autre information. Ayant identifié l'information nécessaire, le SCP envoie un message (3) au poste mobile, par exemple en demandant un code d'autorisation, qui est retournée au MS (11) par le centre de commutation MSC (13) et au poste de base BSS (12) en utilisant un protocole de signalisation. L'utilisateur, ayant reçu le message (3) répond pour que le poste mobile (11) envoie un second signal (4) par le réseau hôte vers le SCP (15). Le SCP (15) agit sur le message reçu et retourne une réponse (5) au MSC (13). Le MSC (13) va utiliser cette information, par exemple pour établir un appel, en prévoyant un canal audio complet si nécessaire (6). Ce système permet à des données d'être transmises directement entre le SCP (15) et l'utilisateur (11), alors que le réseau hôte n'a pas besoin d'être compatible avec les protocoles de signalisation, sauf pour ce qui concerne les étapes initiales et finales (1, 5). En outre, comme on utilise des canaux de signalisation, les canaux audio, ayant une largeur de bande plus importante, ne sont utilisés, seulement si et quand le processus d'appel est terminé.

Inventor: MOON BYUNG II
IPC: F16H37/06
Filed: 1997-11-20
Abstract: The present invention relates to a continuously variable transmission contructed in such a way that it can speed-change the power inputted to an input shaft according to the load applied to an output shaft and transmit the power to the output shaft even though all the gears remain engaged, and in addition reverse operation can also be effectuated in a simple way. Reviewing the construction thereof, it is mainly composed of a speed change system, which receives power generated by an engine, changes speed and transmits it to the output shaft, a speed change controlling system which automatically adjusts the rotational ratio to correspond to the condition of the load on the output shaft, and a reverse rotation system. The present invention, comprises two (compound) gear sets in which each same element is removed from two planet gear sets; and a reverse rotation system, and the power inputted through an input element selected from the two gear sets is changed into the required speed and transmitted to the output shaft. Reviewing the operational characteristics, the present invention is constructed in such a way that the decelerated rotation smaller than the input rotation is transmitted to the impeller by utilizing a direct clutch. Therefore, it is a characteristic of the present invention that the rotational force transmitted to the impeller is always larger than the input torque. In view of the effects, the present invention can obtain a large propulsion force, preferable performance, smooth and quiet operation, and can speed-change steplessly at the time of reverse operation.

Patent CA-2277595-A1 (CA)
Inventor: BLESZYNSKI STANISLAW
IPC: G01F23/296
Filed: 1999-07-02
Abstract: A vibrating probe for detecting a threshold level within a vessel of fluent material, particularly a liquid, includes: an ultrasonic acoustic transducer assembly comprising a transducer element having a natural resonant frequency, and loading elements effective to shift that frequency to an effective resonant frequency of the assembly, the assembly being supported within the vessel and including a coupling member to couple the transducer acoustically to liquid reaching the threshold level, a transmitter generating pulses applied to the transducer element for repeatedly exciting the transducer element to cause the transducer assembly to resonate at its effective resonant frequency, a circuit for measuring the effective resonant frequency of the transducer over a ringdown period following cessation of each pulse, and a circuit for comparing the effective resonant frequency measured during the ringdown period following each pulse with a predetermined threshold level. The threshold level is selected so as to distinguish between the effective resonant frequency of the assembly in free air and a lower effective resonant frequency when coupled to fluent material through the coupling member. The damping effect of the fluent material, particularly if a viscous liquid, may accelerate the ringdown to an extent such that vibration is effectively suppressed before the end of the frequency measurement, thus further depressing the apparent measured frequency.

Patent CA-2279600-A1 (CA)
Title: Swivel drive arrangement
Inventor: POLLACK JACK
IPC: B63B27/24
Filed: 1998-12-02
Abstract: The invention relates to a vessel comprising a hull (1) and a cylindrical turret well (3). The vessel can weathervane around a geostationary turret (4) located in the turret well. At least one swivel (7) is supported on the turret. According to the invention, the inner wall (10) of the swivel is connected to rotation drive means (18), which can thereby be reduced in size and which allow the full swivel weight to be transferred directly to the turret. In one embodiment the inner wall (10) of at least one swivel, preferably the walls of a swivel stack, is rotatably connected to a swivel support structure on the turret via a bearing (17). The rotation drive means (18) are adapted for rotating the inner walls (10) in conjunction with the vessel. In this way relative displacements between the swivel (7) and the turret (4) are reduced such that the layout of the pipe lines connected to the swivel can be simplified by the omission of expansion loops. As the weight of the swivel is carried by the turret, the rotation and pipe support structure can be relatively small. In a second embodiment the outer walls of the swivel stack are fixedly connected to the turret. In this way separate rotational drive means for the outer walls can be omitted.
